.ANTISVIQKIIDDING DEVICE. 7

A ppli catioa filed La in 25, 1925; Serial. No. 25,9ss;

This invention relates to anti-skidding devices, and more particularly to an ant-iskidding deviceadapted for' use upon the wheels of motor driven vehicles, such as automobiles, motor trucks, and the like.

One of the objects of the invention is .to provide a new and improved cross-link device adapted to be used in tire chains of the Weed type, wherein the cross-links are readily removable for the purpose of replacement when worn or broken the construction being such that there is no likelihood of any section or unit of the crosslinks becoming accidentally detached from the circumferentially disposed chain links to which the cross-link units are attached.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

I In the accompanying drawing, wherein I have illustrated a preferred form of embodiment of my invention:

Figure 1 is an elevational view, showing a portion of the anti-skidding chain with my improved cross-link construction connected therewith.

Figure 2 is a view "in longitudinal section of one of the attaching devices; and

Figure 3 is a perspective view of my improved attaching device.

Referring now to the drawing, wherein similar reference characters refer to similar parts throughout the views thereof, the reference numerals 1 and 2 denote the circumferentially disposed chains, the same being of the well known Weed type, and 3 indicates one of the cross-chains, the same being extended in the usual way between the side chains, as shown. 1

4: indicates one of the devices adapted to attach the ends of the cross-chains'to the side chains, said device being formed of wire bent into U-shape, as shown, the U-bend 5 being interlinked with one end of an end link of the cross-chain.

The free ends of the device at are bent upwardly, as at 6, and rearwardly and downwardly, as at 7 said free ends lying in parallel relation, as shown. --The upper surfaces of the free ends 7 are preferably beveled off, as at 8 Y The reference numeral 9 denotes a keeper, the same comprising a triangular strip of spring metal, one end 10 of which is preferably attached to the attaching device 4:, ad jacent the U-shaped bend 5. This keeper may be attached to the said attaching device in any desired manner, preferablyby' spotwelding it thereto. 4

The tapered end 11 of the keeper 9 ex tends forwardly, and is received between the free ends 7 of the attaching device, and is spaced therefrom, as shown at 12. The tapered end 11, it will be noted by reference to Figure 2, lies between the free ends 7 and is substantially parallel therewith.

It will accordingly be seen that I have provided a device well adapted to attain, among others, all the aims and objects above pointed out, in a simple and efficient manner. The construction of the hook device, which is employed to connect the cross chains to the side chains is such as to make it impossible for'the cross-chains .to become accidentally disengaged from the side chains, although the disengaging of the cross-chains from the side chains is accomplishedvery easily, if desired. 7

This it will be seen is accomplished by merely depressing the spring member and removing the link and side chains rearwardly, and then upwardly, whereby the link of the side chain will be slid underneath the tapered portion 11 of the keeper, and over the beveled surfaces 8 of the free ends 7. v

The spacing ofthe tongue 11 of the keeper 9 from the free ends 7 of the attaching device 4, prevents those parts from becoming rusted together, as well as providing a construction whereby mud couldbe readily shaken out and disengaged from the attaching device while the chain is in operation.

'As many changes could be made in this construction without departing from the scope of the following claims, it is intended that .all matter contained in the above description or shown in the accompanying 1. The combination With a cross chain and means for detachably connecting the cross chain with side chains comprising a length of Wire bent into U-shaped form so as to engage one of the links of the side chain, the

free ends of said length of Wire being formed into substantially parallel hooked portions, a keeper mounted upon the. legs of said member and having a portion extending between said hooked portions, and said keeper having its outer end free of either of said hooked end portions and normally in the plane thereof.

2. A hook of the character described comprising a length of Wire bent into U-shaped form and having its free ends bent upon themselves to form spaced lIOOkGCl PjOI'tiOIlS extending in substantially the same direction, the extremities of the hooked portions having theirupper surfaces beveled ofi, a keeper having a tongue Which extends between .the hooked ends of the U-shaped member and terminates adjacent the beveled portions thereof, said tongue being free from either of said hooked ends and normally in the plane thereof.

In testimony whereof, I aflix my signature.
